Their Haswell era machines AW 17 R1 is the last of the originality, which had the laser etched nameplate (it's downgraded to a generic one though) the removable battery bay is moved into the chassis and the bottom plate is weak, the exoskeleton construction is not that thick (Area 51M is even thin), they sandbagged the BIOS with secure trash, thankfully the R1 and AW18 both got unlocked BIOS through a bug. Their latest machines are a frigging joke with all BIOS flash protection, BGA trash no MXM, the 17R1 is the last of that socket machine until that A51M happened but it's already abandoned by them, they got RTX2080 GPU as max and now there's no upgrade for the RTX2080Super which is available on the 51M R2 lol it uses a propreitary trash formfactor called Dell Graphics Form Factor. Also no XMP support, pathetic DRAM speeds, need to use proprietary Dell RAM for Intel spec. Area51M is pure garbage machine which just looks good (even white color gets yellowish), battery gets puffy, shitty BIOS with all PCH flash protection, GPUs get fried by trash TDP voltage tables (HW is not made upto the mark), their desktop machines are a gigantic sink of money dumping by noobs, they didn't even offer BIOS update for the 6th to 7th gen Intel CPU upgrade, that's default from Intel so many issues.
